RecursionError: maximum recursion depth exceeded about chembl_webresource_client

I'm also getting the same issue directly out of the box after python3 -m pip install chembl_webresource_client.

Seems like an issue from gevent solved at: gevent/gevent#903

Yes, please update gevent and on my side I'll sort out dependencies so the correct version of gevent will be installed from the very beginning.

Forgive my ignorance, but would pip install -U gevent be the only thing required to bypass this error? I am still receiving it with python 3.6, gevent 1.2.2, chembl_webresource_client 0.9.13 (and all other dependencies up to date).

[mnowotka]

Yep, this is what is suppoosed to happen. Can you please confirm you executed this command successfully and still gettng the error? In that case I'll try to create a conda environment with exactly this software versions and repoduce the problem and get back to you, OK?

That sounds like a lot of work from you - I just might be an idiot (new to working with Python). Is there any information I can provide to identify any gotchas before you put in this time? Thanks for all your help.

From your comment, I poked around and learned how to use conda to set up environments. This is very handy! With python 3.5.2 and the dependencies requested by the latest chembl_webresource_client (that is - only gevent 1.1.2), everything works swimmingly. Thank you for indulging a newbie.

Great stuff, sorry for the late reply, I'm on holidays right now but I wanted to suggest exactly what you did. Anyway, would you care to execute pip freeze outside of any conda env (so effectively in your old problematic environement) and paste the output in the comments so I can investigate this particular combination of versions and see how I can resolve the problme in this case?

[writes-awful-code]

The output of my pip freeze outside of the working conda environment is as follows:

certifi==2017.7.27.1
chardet==3.0.4
chembl-webresource-client==0.9.13
easydict==1.7
gevent==1.2.2
greenlet==0.4.12
grequests==0.3.0
idna==2.5
lxml==3.8.0
requests==2.18.3
requests-cache==0.4.13
six==1.10.0
urllib3==1.22

This was on python 3.6.2 on Windows 10. Here's hoping I'm not crazy...

Great, thanks, that's really helpful!

[mnowotka]

This is now fixed for good. Sorry for keeping you waiting for that long.
